Traditional
vehicle management is to install GPS/Beidou positioning terminal. Install float
type oil level sensor. This approach does address individual issues in the
early stage, such as monitoring vehicle position, tracking vehicle tracks and
monitoring fuel tank oil level. But this kind of monitoring is coarse, the
accuracy is low, false report much.

In response to this situation, Soway has developed a series
of vehicle status monitoring sensors for the market demand and the
characteristics of the commercial concrete industry.

1. The SFCG20L oil sensor can
effectively monitor the oil level of oil tank, prevent oil theft, record the
oil tank quantity, the number of times of refueling, etc. Capacitive liquid
level sensor used agent is formed between pole and container capacity has a
linear variation law with the liquid level, the level of variation is converted
into linear output, can be directly display liquid level height or transmitted
by wireless sent directly to the remote monitoring system. The same sensor can
change the measurement medium or change the installation environment at any
time, without the need to re-calibrate all the automatic adaptation and
accurate measurement, without the influence of dielectric constant and
temperature change. For example a SFCG type automobile oil level sensor mounted
to the tanker, the car from moving south to the north of our country,
regardless of the label of its fuel replacement, or need to add any additives
calibration can accurately measure the oil level. And temperature, RF
interference and other factors have no effect on the sensor.

2. HOCM high-precision fuel
consumption meter, also known as fuel consumption meter, which is installed in
and back oil; Fuel consumption instrument is using the positive displacement
principle to implement state monitoring on vehicle fuel consumption, the
measuring accuracy is not affected by oil change, bumpy road, the
characteristics of small volume, light weight, seismic, by monitoring the
vehicle oil line of instantaneous flow and cumulative flow, total time, optimal
operation, makes concrete mixing on the shorter time, full use of the vehicle,
the fuel consumption can be reduced, such as spending to reduce vehicle fuel
consumption.

3. The SPH3A0 series positive and
reverse rotational speed sensor is tested by Hall principle. Just in the shaft
or round detection in fixed 2 magnets (two magnets symmetric distribution, and
must be a magnet N pole toward the sensor, the other magnet S pole toward the
sensor installation), the sensor probe test the arrow in the face of the magnet
rotating arc fixed well. When the wheel or shaft is rotating, with the magnet
along the direction of the arrow to sweep the sensor probe, the output of line
2 is turning signal (low level), and the output of line 4 is turning the speed
pulse signal; On the other hand, the output reversal signal of line 2 (high
level), and no. 4 output reversal speed pulse signal.

4. SDVH36 load sensors work
according to the principle of inductance. Because the weight change causes the
spring deformation of the steel plate to produce the displacement, the
displacement is measured and the related circuit is converted into voltage
output. The platform calculates the load based on the change in voltage. Load
sensors can monitor the load status of vehicles, such as empty load, full load,
overload, overload, etc.

Note:

1. The above sensors are all individual
hardware devices; Can be used with terminal equipment and network platform; The
sensor is responsible for collecting data and sending the GPS/Beidou terminal
device to the monitoring platform (such as ERP system).

2. The sensor provides basic data, and the
platform needs to screen, analyze and process data, and implement various
applications.

3. For users who do not have GPS installed,
the transmission module can be installed to collect the data into the office
management platform.
